NotesThis is an inert display round with no powder or primer. Production MK 149 MOD 2 rounds feature a depleted uranium penetrator. The penetrator in this specimen attracts a magnet so it is not DU. It also does not register on a geiger counter. It may be steel or possibly tungsten. Note the unusual sabot design compared to later MK 149 MOD 2 cartridges.
